- Combines the benefits of hermetically sealed electronics with tangential turbine technology to deliver precise flow control and monitoring even under the most extreme conditions.
- For remote flow monitoring, a 2-wire loop-powered arrangement sends a 4 to 20 mA signal proportionate to flow rate.
- A clear polycarbonate viewing cover is available to provide a visual flow indicator.
- Additional protection is provided by the 316 SS cover, which has a 500 psig (34 bar) pressure limit.
- LED power indicator, polarity protection, adjustable zero and span, and overcurrent limitation.
- Measures flow accurately in both directions and is orientable for mounting.
